Issues After Moving/Deleting Messages - More Info Needed

We apologize for the issue you are experiencing after moving to our
new Preview.
Moving to the next message after a move or delete is a
configurable option both in the old and the new experience. Is the
behavior you are seeing now different than before you were moved to the new
Preview?

You can change the option as follows:
1. Click on the gear menu in the top right and select
"Options". This will take you to our Options page
2. On the left-hand side click "Message options" (under
Mail -> Automatic processing)
3. Change "After moving or deleting an item" to be "Open
next item"
4. Click the Save button near the top
5. In the left-hand pane click the <- Options button to go back to
your mailbox

Please let us know if you are still having problems after this or
if any of the above is unclear.
